Abstract (en)
[origin: US6375463B1] Improved dental wedges having gritty top layers are disclosed that enable instruments to easily engage the dental wedges and position them between the two teeth. The wedges may have gritty layers that are positioned on their proximal ends through use of an adhesive or by molding techniques. Each gritty top layer includes a grit material such as aluminum dioxide and an attachment material such as acrylics.
